Please help me solve part a$-$c thank you!

Develop the system curve for the system presented below. Solve the conservation of energy equation for the head added $)$ using the lower reservoir as your first reference point and the upper reservoir as your second reference point. Do not account for minor losses in the system curve. $($Note see the specifics below$)$

Your result will have the following format: $h_P=+Q^2$

a$.$ Develop the system curve for the system represented in the Figure by solve the conservation of energy equation for the head added $($ hP $)$ using the lower reservoir as your first reference point and the upper reservoir as your second reference point. Neglect minor losses using the Darcy Equation.

b$.$ For the system shown in the Figure compute the system curve using the Hazen$-$William Equation. Assume that the C value for the suction and discharge pipelines is $120$ for both. Keep the length and diameter the same and neglect minor losses once again.

c$.$ Create a graph comparing the system curves created using the Darcy$-$Weisbach and Hazen$-$Williams approaches. Show both lines on one graph $($as opposed to created two separate graphs$).$
